BACKGROUND OF THE INVENTION

Described are alkyl-substituted tetra- or hexahydrobenzopyran derivatives defined to one of the structures: ##STR5## wherein Z is in the alternative one of the moieties: ##STR6## wherein in the moiety: ##STR7## R' is methyl or ethyl and in the moiety: ##STR8## one of the dashed lines is a carbon-carbon double bond and each of the other of the dashed lines represent carbon-carbon single bonds; wherein R₁ and R2 taken separately are hydrogen or C₁₋₃ lower alkyl or R₁ and R2 taken together complete a C₅ or C₆ cycloalkyl moiety as well as organoleptic uses thereof in augmenting or enhancing the aroma of perfume compositions, colognes or perfumed articles.

There has been considerable work performed relating to substances which can be used to impart (alter, modify or enhance) fragrances to (or in) various consumable materials. These substances are used to diminish the use of natural materials some of which may be in short supply and to provide more uniform properties in the finished product.

Floral, magnolia, fruity, citrusy, peach, natural liatrix-like, green, hay-like, lactonic sweet, coumarin-like, coconut-like, buttery, jasmine, minty, dry and woody aromas with green, herbaceous, coriander seed-like, fruity, peach, celery-like, jasmine and lactonic undertones and citrusy, orange-peel-like, minty, herbaceous and buttery topnotes are highly desirable in several types of perfume compositions and for use in perfumed articles.

Arctander "Perfume and Flavor Chemicals (Aroma Chemicals)", Volume I, 1969, at Monograph 1053 discloses the use of the compound having the structure: ##STR9## in augmenting or enhancing the aroma of perfume compositions. This material, commonly known as dihydrocadinol is disclosed to have a powerful and very dry, musty, woody odor of similarity to the dry notes of ambergris. As indicated that it can be used to give a "lift" to a number of non-floral fragrance types and in combination with galbanum, oakmoss and the like it may form a very important part of certain types of luxury perfume. The compound having the structure: ##STR10## is difficult to synthesize and relatively expensive. In addition, the compounds of our invention have nuances distinctly advantageous over the compound having the structure: ##STR11## and have even a greater strength, tenacity and substantivity.

Referring to FIGS. 18 and 19, there is provided a process for forming scented polymer pellets (wherein the polymer may be a thermoplastic polymer such as low density polyethylene or polypropylene or copolymers of ethylene-vinyl acetate or mixtures of a polymer and copolymer such as a copolymer of ethylene-vinyl acetate and polyethylene) such as pellets useful in the formation of plastic particles useful in fabricating certain articles which may be perfumed. This process comprises heating the polymer or mixture of polymers to the melting point of said polymer or mixture of polymers, e.g., 250° C. in the case of low density polyethylene. The lower-most portion of the container is maintained at a slightly lower temperature and the material of the container is taken off at such location for delivery through the conduit. Thus, referring to FIGS. 18 and 19, in particular, the apparatus used in producing such elements comprises a device for forming the polymer containing perfume, e.g., polyethylene or polyethylene-polyvinyl acetate or mixtures of same or polypropylene, or the like, which comprises a vat or container 212 into which the polymer taken alone or in admixture with other copolymers and a perfuming substance containing at least one of the alkyl-substituted tetra- or hexahydrobenzopyran derivatives of our invention is placed. The container is closed by means of an air-tight lid 228 and clamped to the container by bolts 265. A stirrer 273 traverses the lid or cover 228 in an air-tight manner and is rotatable in a suitable manner.

A surrounding cylinder 212A having heated coils which are supplied with electric current through cable 214 from a rheostat or control 216 is operated to maintain the temperature inside the container 212 such that the polymer in the container will be maintained in the molten or liquid state. It has been found advantageous to employ polymers at such a temperature that the viscosity will be in the range of 90-100 sayboldt seconds.

Heating means (coils 212A) are operated to maintain the upper portion of the container 212 within a temperature range of, for example, 250-260° C. in the case of low density polyethylene. The bottom portion of the container 212 is also heated by means of heating coils 212A regulated through the control 220 connected thereto through a connecting wire 222 to maintain the lower portion of the container 212 with a temperature range of 225-240° C.

Thus, the polymer or mixture of polymers added to the container 212 is heated from 10-12 hours, whereafter the perfume composition or perfume material containing at least one of the alkyl-substituted tetra- or hexahydrobenzopyran derivatives of our invention is quickly added to the melt. Generally, about 10-45 percent by weight of the resulting mixture of the perfumery substance is added to the polymer.

After the perfume material containing at least one of the alkyl-substituted tetra- or hexahydrobenzopyran derivatives of our invention is added to the container 212, the mixture is stirred for a few minutes, for example, 5-15 minutes and maintained within the temperature ranges indicated previously by the heating coils 212A. The controls 216 and 220 are connected through cables 224 and 226 to a suitable supply of electric current for supplying the power for heating purposes.

Thereafter, the valve "V" is opened permitting the mass to flow outwardly through conduit 232 (also indicated by reference numeral 218 in FIG. 18) having a multiplicity of orifices 234 adjacent to the lower side thereof. The outer end of the conduit 232 is closed so that the liquid polymer intimately admixed with at least one of the alkyl-substituted tetra- or hexahydrobenzopyran derivatives of our invention will continuously drop through the orifices 234 downwardly from the conduit 232. During this time, the temperature of the polymer intimately admixed with the perfumery substance in the container 212 is accurately controlled so that a temperature in the range of from about 240-250° C. (in the case of low density polyethylene) will exist in the conduit 232. The regulation of the temperature through the controls 216 and 220 is essential in order to insure temperature balance to provide for the continuous dropping or dripping of molten polymer intimately admixed with the perfume substance containing at least one of the alkyl-substituted tetra- or hexahydrobenzopyran derivatives of our invention through the orifices 234 at a rate which will insure the formation of droplets 236 which will fall downwardly onto a moving conveyor belt 238 caused to run between conveyor wheels 240 and 242 beneath the conduit 232.

When the droplets 236 fall onto the conveyor 238, they form pellets 244 which harden almost instantaneously and fall off the end of the conveyor 238 into a container 250 which is advantageously filled with water or some other suitable cooling liquid to insure the rapid cooling of each of the pellets 244. The pellets 244 are then collected from the container 250 and utilized for formation of other functional products, e.g., garbage bags and the like.

SUMMARY OF THE INVENTION

Our invention relates to alkyl-substituted tetra- or hexahydrobenzopyran derivatives defined according to the structure: ##STR41## as well as the structure: ##STR42## wherein Z is a moiety selected from the group consisting of: ##STR43## and wherein R' is methyl or ethyl; wherein in the moiety: ##STR44## one of the dashed lines is a carbon-carbon double bond and the other of the dashed lines are carbon-carbon single bonds; and wherein R₁ and R₂ taken separately are hydrogen or C₁₋₃ lower alkyl or R₁ and R₂ taken together complete a C₅ or C₆ cycloalkyl moiety.

Our invention also relates to organoleptic uses of such alkyl-substituted tetra- or hexahydrobenzopyran derivatives as defined, supra, in augmenting or enhancing the aroma of perfume compositions, colognes or perfumed articles, including but not limited to solid or liquid anionic, cationic, nonionic or zwitterionic detergents, fabric softener compositions, fabric softener articles, hair preparations, cosmetic powders and perfumed polymers.

Our invention is also related to processes for preparing such alkyl-substituted tetra- or hexahydrobenzopyran derivatives by means of reacting isopulegol having the structure: ##STR45## or an isomer thereof having the structure: ##STR46## with a pre-prepared ketal or acetal having the structure: ##STR47## according to the reaction: ##STR48## or the reaction: ##STR49## (wherein R', R₁, R₂ and Z are defined, supra).

The ketals or acetals are prepared by reacting the appropriate aldehyde or ketone with an acetal or ketal-forming reagent (e.g., a trialkylorthoformate) according to the reaction: ##STR50##

In the alternative, isopulegol per se may be reacted with an aldehyde (without the acetal formation) according to the reaction: ##STR51##

When isopulegol is used as a reagent; and when an acetal is used as a reactant, the mechanism of the reaction is as follows: ##STR52##

In general, when a ketal is used as a reagent, or an acetal is used as a reagent in the reaction with isopulegol the mechanism is shown as follows: ##STR53##

When the reaction is one which takes place between isopulegol and an aldehyde, the mechanism is as follows: ##STR54##

When the reaction takes place between an acetal and the isomer of isopulegol having the structure: ##STR55## the mechanism is as follows: ##STR56##

When the reaction takes place between a ketal or acetal and the isomer of isopulegol having the structure: ##STR57##

The reaction temperature (between the isopulegol or isopulegol isomer and the acetal, ketal or aldehyde (as the case may be)) may vary between about 75° C. and 100° C. depending upon the particular acetal used.

The reaction takes place in the presence of a catalytic amount of protonic acid, preferably concentrated sulfuric acid (as more specifically set forth in the examples). The reaction takes place over a period time of between about one hour and about three hours.

The mole ratio of aldehyde or ketone to isopulegol or isopulegol isomer may vary from about 2 moles (aldehyde or ketone):1 mole isopulegol or isopulegol isomer down to about 1 mole (aldehyde or ketone):1 mole isopulegol or isopulegol isomer.

At the end of the reaction the reaction mass is neutralized and the organic phase is preferably dried and fractionally distilled in order to yield organoleptically suitable product useful for incorporation into perfume compositions, colognes and/or perfumed articles

At least one of the alkyl-substituted tetra- or hexahydrobenzopyran derivatives of our invention and one or more auxiliary perfume ingredients including, for example, alcohols other than the alkyl-substituted tetra- or hexahydrobenzopyran derivatives of our invention, aldehydes, nitriles, esters, cyclicesters, ketones, ethers other than the alkyl-substituted tetra- or hexahydrobenzopyran derivatives of our invention, natural essential oils and synthetic essential oils may be admixed so that the combined odors of the individual components produce a pleasant and desired fragrance particularly and preferably in floral and "tropical" fragrances.

Such perfume compositions usually contain (a) the main note or "bouquet" or foundation stone of the composition; (b) modifiers which round off and accompany the main note; (c) fixatives which include odorous substances which lend a particular note to the perfume throughout all stages of evaporation and substances which retard evaporation; and (d) topnotes which are usually low-boiling, fresh smelling materials.

In perfume compositions, it is the individual components which contribute to its particular olfactory characteristics, but the over-all effect of the perfume composition will be the sum of the effects of each of the ingredients. Thus, one or more of the alkyl-substituted tetra- or hexahydrobenzopyran derivatives of our invention and one or more auxiliary perfume ingredients can be used to alter the aroma characteristics of a perfume composition, for example, by utilizing or moderating the olfactory reaction contributed by at least one other ingredient in the composition.

The amount of at least one of the alkyl-substituted tetra- or hexahydrobenzopyran derivatives of our invention useful in perfume compositions for augmentation or enhancement of floral, magnolia, fruity, citrusy, peach, natural liatrix-like, green, hay-like, lactonic, sweet, coumarin-like, coconut-like, buttery, jasmine, minty, dry and woody aromas with green, herbaceous, coriander seed-like, fruity, peach, celery-like, jasmine and lactonic undertones and citrusy, orange-peel-like, minty, herbaceous and buttery topnotes may vary from about 1% by weight of the perfume composition up to 100% by weight of the perfume composition (the entire composition can be composed of the alkyl-substituted tetra- or hexahydrobenzopyran derivatives of our invention).

At least one of the alkyl-substituted tetra- or hexahydrobenzopyran derivatives of our invention and one or more auxiliary perfume ingredients can be used to impart such aroma nuances, topnotes and undertones to soaps, anionic, cationic, nonionic or zwitterionic detergents, fabric softener compositions, fabric softener articles, cosmetic powders, hair preparations and the like. The amount employed can range up to 100% by weight of the fragrance components and can range up to approximately 0.5% of the weight of the perfumed article and will depend upon considerations of cost, nature of the end product, the effect desired on the finished product and the particular fragrance sought.

At least one of the alkyl-substituted tetra- or hexahydrobenzopyran derivatives of our invention and one or more auxiliary perfume ingredients are useful, taken alone or in perfume compositions as olfactory components in anionic, cationic, nonionic or zwitterionic detergents, soaps, fabric softener compositions, fabric softener articles for use in clothes dryers (e.g., "BOUNCE®", a registered trademark of the Procter & Gamble Company of Cincinnati, Ohio), space odorants and deodorants, perfumes, colognes, toilet waters, bath preparations, such as lacquers, brilliantines, creams, deodorants, hand lotions and sun screens; powders, such as talcs, dusting powders, face powders and the like.

When used as an olfactory component in perfume compositions or perfumed articles, such as anionic, cationic, nonionic or zwitterionic detergents and fabric softener compositions and fabric softener articles (e.g., for use in clothing dryers) as little as 0.05% of at least one of the alkyl-substituted tetra- or hexahydrobenzopyran derivatives of our invention and one or more auxiliary perfume ingredients will suffice to impart aroma nuances as set forth, supra. Generally, no more than 0.5% of at least one of the alkyl-substituted tetra- or hexahydrobenzopyran derivatives of our invention and one or more auxiliary perfume ingredients based on the ultimate end product is required in the perfumed article.

In addition, the perfume composition or fragrance composition of our invention can contain a vehicle or carrier for at least one of the alkyl-substituted tetra- or hexahydrobenzopyran derivatives of our invention and one or more auxiliary perfume ingredients. The vehicle can be a liquid such as a non-toxic alcohol, a non-toxic glycol, or the like. The carrier can also be an absorbent solid, such as a gum (e.g., gum arabic, xanthan gum or guar gum) or components for encapsulating the composition (such as gelatin as by means of coacervation).

It will thus be apparent that at least one of the alkyl-substituted tetra- or hexahydrobenzopyran derivatives of our invention and one or more auxiliary perfume ingredients can be used to alter the sensory properties, particularly organoleptic properties of a wide variety of consumable materials.

The following Examples I-VI are illustrative of processes for preparing the alkyl-substituted tetra- or hexahydrobenzopyran derivatives of our invention. Examples VII, et seq. are illustrative of the organoleptic utilities of the alkyl substituted tetra- or hexahydrobenzopyran derivatives of our invention. However, the invention is to be considered restricted thereto only as indicated in the appended claims.

All parts and percentages given herein are by weight unless otherwise specified.

EXAMPLE XVIII

Each of the fragranced materials of Table II of Example X, supra, are added to a 50:50 weight:weight mixture of low density polyethylene:polyepsilon caprolactone PCL-700 forming pellets with scents as set forth in Table II of Example X, supra.

75 Pounds of a mixture of PCL-700 polyepsilon caprolactone (manufactured by the Union Carbide Corporation of New York, N.Y. having a melting point of about 180°-190° F.):Low density polyethylene are heated to about 250° C.. in a container of the kind illustrated in FIGS. 18 and 19. 25 Pounds of each of the fragrance materials as set forth in Table II of Example X is then quickly added to the liquefied polymer mixture, the lid 228 is put in place and the agitating means 273 are actuated. The temperature is then raised to about 260° F. and the mixing is continued for 5-15 minutes. The valve "V" is then opened to allow flow of the molten polymer enriched with perfume ingredient to exit through the orifices 234. The liquid falling through the orifices 234 solidified almost instantaneously upon impact with the moving cooled conveyor 238. Polymer beads or pellets 244 having pronounced scents as described in Table II of Example X, supra, are thus formed. Analysis demonstrates that the pellets contain about 25% of the perfume material so that almost no losses in the scenting substance did occur. These pellets may be called "master pellets".

50 Pounds of each batch of the scent containing "master pellets" are then added to one thousand pounds of unscented polypropylene and the mass is heated to the liquid state. The liquid is molded into thin sheets of films. The thin sheets of films have pronounced aromas as set forth in Table II of Example X, supra. The sheets of films are cut into strips of 0.25" in width x 3" in length and placed into room air fresheners.

On operation of the room air freshener, after four minutes, the room in each case has an aesthetically pleasing aroma with no foul odor being present, the aroma being described in Table II of Example X, supra.
